Kioxia sampling latest generation UFS Ver. 4.0 embedded flash memory devices
Kioxia has announced that it has begun sampling the latest generation of its Universal Flash Storage (UFS) Ver. 4.0 embedded flash memory devices. Supported in capacities of 256 gigabytes (GB), 512GB, and 1 terabyte (TB), the new products are well suited for a variety of next-generation mobile applications, including leading-edge smartphones.
The enhanced performance of the new UFS products provides optimal utilisation of 5G connectivity, resulting in accelerated downloads, minimised latency, and an enhanced user experience. A smaller package size contributes to board space efficiency and design flexibility.
Kioxia was the first to introduce UFS technology and continues to develop new products. The latest UFS Ver. 4.0 devices integrate the company’s innovative BiCS FLASH 3D flash memory and a controller in a JEDEC standard package. UFS 4.0 incorporates MIPI M-PHY 5.0 and UniPro 2.0 and supports theoretical interface speeds of up to 23.2 gigabits per second (Gbps) per lane or 46.4 Gbps per device. UFS 4.0 is backward compatible with UFS 3.1.
Sample shipments for the 256 and 512GB products begin this month, with the 1TB offering following in June 2024.
